"UEFA have City third in the table... The Mail, Times, Mirror, Star, Guardian, Tele has them fourth," Clayton tweeted, followed by the hashtagged exclamation "#huh?"
There's an important rider: Clayton also suggested that the overworked subs on the Express sports desk have City in second place in UEFA's qualifying group, with one crucial game to play to determine who goes into the lucrative knock-out stages in the new year.
Maybe Clayton was looking at a different edition, because in the copy of the paper I bought in London this morning, the hard-pressed Express sports desk appears to be the only national paper which has reproduced the Group E table to match the European football governing body. Not that that is an guarantee of being correct...
In this case, that would put City in second place.
City - thanks largely to Aguero - have scored 7 and conceded 8, and so have a goal difference of -1, ahead of the -4s of Roma and Moscow, with the Italian club adjudged to have the advantage of the Russian club by virtue have having scored two goals more.
But this is a competition organised by the Swiss-based gnomes of European football, and so "normal" does not apply.
UEFA's own website, which has City in third with just one game to play, in Rome next month, has the weasel word cop-out, "Standings are provisional until all group matches have been played", which is all fine and dandy for them, but is no bloody good for a sports desk sub on deadline in London on a Tuesday night.
And according to UEFA's own competition rules, the table on their website (and therefore in the Express) is incorrect.
With a place in the last 16 worth around £20 million to each of the successful clubs, these distinctions matter.
Nick Harris, who covers sports news (bribes 'n drugs) for the Mail on Sunday as well as running the ever-excellent sportingintelligence.com website is a bit of an anorak in these respects, and he has highlighted how the H2H records take precedence, and therefore ought to see City at the foot of the group table.
Pity the poor sports subs, eh?
For anyone with the time and inclination to try to work out how this all works (not that it will matter by the time of the final whistle in Stadio Olimpico), the Mail has had a bash at explaining it all here.
And in the meantime, I - probably backed by the Express - am about to start a campaign called "Bring Back Sir Stanley Rous!"
